Title: Lamp monitoring circuits.
IPC: B60Q11/00
Filed: 1983-09-27
Abstract: It is an object of the invention to provide a circuit which will indicate failure of a motor vehicle bulb, even when the bulb is not illuminated, i.e. cold monitoring. This is achieved by the provision of a potentiometer R1, R2 and R3 with the lamp effectively connected across R2, R3 and a detecting transistor connected to a point C between R2 and R3. A small monitoring current is feed through the lamp L in the cold state and this keeps the potential at point A at a low level so that the transistor Q is not biased into conduction by the potential at the points C. Should the lamp fail, the potential at point A rises and transistor Q is biased into conduction to operate an audible and/or visual warning. In order to provide for hot monitoring, a reed switch Y is provided to earth the point A when the lamp is drawing current from the supply line B. If the lamp fails, the reed switch opens and the circuit functions as for cold monitoring.

Title: Arrangement for determining the travel of a piston
IPC: G01B7/02
Filed: 1984-04-24
Abstract: A contactlessly, measuring arrangement for determining the position of a piston in a suspension component such as a vibration damper, gas spring or hydro-pneumatic suspension. In one embodiment, the piston and/or the piston rod of the suspension component and a further electrode are mounted inside the cylinder of the suspension component to form a variable capacitor which, with the aid of other circuitry, measures the position of the piston. The further electrode preferably is in the form of a tube extending from the base of the cylinder into a hollow cylinder formed within the piston rod which receives the tube. In the capacitive embodiment, additionally, there may be provided a further tube within the first tube to form a reference, second capacitor which is sensitive to pressure and temperature in the same manner as the first capacitor. The first capacitor serves as the variable capacitor for making a position measurement of the piston and the two tubes fixed relative to one another are employed to form the reference capacitor. In an alternative embodiment, the outer surface of the cylinder has an inductive coil wound therearound for producing a magnetic field which is variable dependent upon the position of the piston within the cylinder. Both measuring arrangements when connected in a Wheatstone Bridge circuit produce an electrical signal indicative of the position of the piston.
